Which term describes a patient who is at risk of decompensation but currently not unstable?

• A. Stable
• B. Potentially unstable
• C. Unstable
• D. Critical

Answer: (B)

The concept here is distinguishing current status from future risk. A patient who is not unstable right now but who could deteriorate is described as potentially unstable. This label acknowledges that the person has indicators or factors suggesting they may decompensate if not treated or if their condition worsens, so they require close monitoring and readiness to intervene, even though their present vitals and presentation aren’t critically abnormal.

Think of someone with chest pain who is currently hemodynamically stable but has ongoing symptoms or risk factors for a heart event, or a patient with shortness of breath who is maintaining adequate oxygenation but shows signs that fatigue and work of breathing could worsen. In both cases, you aren’t seeing instability at this moment, but there’s a real risk of rapid change, so the patient is managed with vigilant reassessment and readiness to escalate.

This differs from stable, which implies no current threat of decompensation; unstable, where there are clear signs of decompensation right now; and critical, which indicates life-threatening status requiring immediate, aggressive intervention.
